Residents and business owners in certain of Pasadena can now experience ultra-fast internet speeds after AT&T launched new fiber optic services in the city which offer 1-gigabit-per-second connection speed.

A one-gigabit connection is 20 times faster than the average cable connection, AT&T said.

For example, the company said, a user logged into the service can download 25 songs in one second, or a 90-minute HD movie in less than 34 seconds.

The ultra-fast speeds also let users seamlessly telecommute, video-conference, upload and download photos and videos, and connect faster to the cloud, AT&T said.

The 100 percent fiber network under the AT&T Fiber umbrella brand gives customers the power to choose from a wide range of internet speeds over an ultra-fast internet connection.

AT&T says it has invested more than $2.1 billion in its wireless and wireline networks in the greater Los Angeles area between 2013 through 2015.

“AT&T continues to invest in Southern California to bring high-speed internet to our customers,” Mike Silacci, assistant vice president at AT&T California, said. “The Greater Los Angeles area is home to technology, entertainment, and a variety of growing industries. AT&T Fiber will help all of business grow and thrive.”
